BS EN 23995:1993 金属粉末规范.矩形压坯横向断裂压坯强度的测定

This International Standard specifies a method for the deter-mination of green strength by measuring the transverse rupture strength of compacts of rectangular cross-section.

BS EN 23923-2:1993 金属粉末 表观密度的测定 斯科特容量计法

This part of ISO 3923 specifies the Scott volumeter method for the determination of the apparent density of metallic powders. It is applicable to powders that will not flow freely through a 5 mm orifice (see ISO 3923/1). Part 3 of this International Standard specifies the oscillating funnel method for the determination of apparent density of such powders, and this is preferred since it gives better preci-sion, but it cannot be used in cases where the powder may change its properties due to the vibration action applied to the powder during testing.
